To use or not to use "Zebra Stripes", or Alternating Row Colors for Tables

I generally find it easy to associate the input fields with the row names as long as the table is formatted correctly. So, I am not sure if alternating the colors actually adds to the user experience, but I guess I can see why this is stylistically appealing.
